|In 1933, J.C. Gorman and Herb Rupp introduced a pump which had a "non-clogging" feature. Their competitors claimed the pump would not work in a savage public awareness campaign to discredit the new design, which resulted in about $100,00 worth of "free advertising." At least one customer was willing to try it. National Ice Company purchased the first pump, and the company Gorman-Rupp was established. Photo courtesy of Gorman-Rupp Company.|
1994 Two new major products are introduced by Goulds Pumps, the Industrial Model 3298 Magnetic Drive Pump and the Water Technologies Model GS “Global Submersible.”
1994 Sims receives the honor of approval from the United States Navy for composite centrifugal pump intervals. Simsite was tested and qualified for centrifugal pump replacement parts and was the first composite to be certified.
1994 Baha Abulnaga invents the slurry and froth pump with a split vane impeller. The split impeller helps to reduce recirculation in slurry pumps by dividing the space between the main vanes without reducing the passageway at the narrowest point, which is the eye of the impeller. In froth pumps, it helps to break up air bubbles that form and tend to block the flow.
1995 Sims manufactures the largest structural composite pumps in the world - two Simsite vertical turbine pumps for Potomac Electric Power Company. They are 40 feet long and 3 feet in diameter.
1997 ITT Industries acquires Goulds Pumps, making ITT the world's largest pump company.
1999 PumpSmart is introduced at the ChemShow in New York.
